BOTTLE-FILLING DEVICE.

Application filed September 2G, 1918.

To all whom it may concern: A

lle it known that l, Di'LLoN C. DANNEL- mir, a citizen of the United States of America, residing at Dallas, in the county ot Dallas and State ot Texas, have invented new and useful Improvements in Bottle-FillingDevices, ot' which the 'following is a speciiication.

rThis invention relates to a new and useful torni ot bottle lling device, and in particular does it relate to a filling machine for charging and filling bottles with carbonated beverages such as soda pops and other drinks.

A purpose ot the invention is to provide al machine capable of simultaneously handling two liquids and introducing` them into the bottle at the same time under pressure. lstill further purpose ot the invention is to provide a means ot automatic control for regulating and governing the flow ot each liquid into the bottle to be charged at the time the machine is brought down upon the bottle and in filling contact therewith.

lilith the above and other objects in view the invention has relation to a certain conibination and arrangement or parts, :an example ot which is described in the following specilication, pointed out in the appended claims, and illustrated in the accoiupuir Y ing drawings; wherein,

Figure 1 illustrates a longitudinal sectional view ot the bottle filling device, shown mounted upon operative standards and above bottles to be iilled.

Fig. 2 illustrates parts ot a certain valve control mechanism in plan view, the view being taken upon the line 2 2 of Fig. 1.

Fig. 8 illustrates a view taken upon the line 3 3 of Fig. 1.

Fig. 4 illustrates a sectional view taken upon the line #l/l of Fig. 1, illustrating certain valve control mechanisms.

Referring now more in particular to the drawings, wherein the sam-e parts throughout are designated by the lsame reference characters, the numeral 1 designates an integral metallic casting or head member provided with the various passages and operating parts which comprise the machine constituting this invention. ln the upper vportion of the device is formed a cylindrical bore chamber 2 which is reduced in size to form a syrup chamber 3. Pistons 4t and 5 are provided in the respective cylinders 2 and 3. Piston rods 6 and 7 are integrally formed one Specification of Letters Eatent.

with the other and carry the pistons and 5 fixed thereupon. For convenience in assembling the rod 7 may be made slightly smaller than the piston rod G. 8 is screw-threaded upon the upper end ot' the device and adapted to hermetically seal the cylinder'. A bushing` 9 is screw-threaded into the cover lcap 8 and vslidably contains the piston rod 7. A compression spring 113 is conlined upon the outer end of the piston rod between a head 11 and a head formed on the outer end of the bushing. The piston under the resisting compression ot the springl 10 may be moved downwardly in the cylinders until the head 11 contacts the end ot the bushing. By screwing the bushing in or out ot the cylinder the travel ot the pistons therein may be regulated and made to travel substantially the entire length of the cylinder or only part thereof. lVithin the lower portion ot the device is confined a 'l-)acking` gland 12 formed of rubber or any' suitable material suiiicient to give contractive compressibility capable of obtaining a liquid and air tight hermetically sealed joint about the open neck ot the bottle. his gland is partly contained within a hinged cap 13 pivoted at 1% to the casting. Just above the packing gland 12 and carried in contact therewith is another gland or washer 15 of substantially the same size and form as the packing gland 12. This member 15 will not necessarily be formed ot a material as yieldable and as flexible as the gland 12, tor the reason that it will not be called upon to perform the same Yfunction of hermetieally sealing the bottle as the originally named 2gland 12. vWithin this member 15 are 'formed certain passages for conveyingair and liquids as hereinafter explained. The two members 12 and 15 are annularly formed and provided with a centrally cylindrical opening 1G of a size substantially the same as the outer diameter' of the neck of the bottle to be filled. A crowning plunger 17 is carried within a cylindrical chamber 1S 'formed in the casting above the packing glands. 4This plunger is provided with a slot 19 `formed normal to the axis of the plunger 17. A screw 20 is screw-threaded into the device and registers within the slot 19 thus confining- 'the plunger to its chamber. The plunger is hollow-bored and fitted with a compression spring 21 confined within the plunger and against the upper head ot the cylinder and adapted to keep the A cover cap' plunger in a normally downwardly limited position. This crowning plunger-17 is provided 'or the purpose of pressing the cover cap or crown of the bottle upon the neck thereof sealing same after said bottle has been llled. One form of crown or bottle cover 22 is shown in position and ready to be driven home by the plunger and action of the device as later described.

A duct or passage 23 extending the length of the casting communicates the upper cylinder with the opening 16 'formed in the member 15. This duct or passage, as laterdescribed, will carry a certain air pressure to be drawn fromthe bottle. Another duct or passage 24 is formed `in the casting and opens into the lower portion of the cylinder 3. A tube lor pipe -25 connects with the passage 24 and is provided with a cut ott' valve 26. This 4tube is downwardly directed and adapted to open in the position illustrated just abovel the `bottle placed thereunder. Another passage 27 connects with the cylinder 3 and extends downwardlywhereit registers with a passage 28 formed in the mem* ber 15. This syrup outlet passage 27 is enlarged at the lower extremity thereof and provided with a valve 29 adapted to govern the flow of the liquid through said passage. A syrup intake passage or duct 30 connects with the cylinder 3 and communicates with a tube31 which is provided with a valve 32. This last named duct, as will later be seen, is provided to lead into the iilling device a regulated quantity of syrup beverage 'to beintroduced into the bottle. A passage or duct 33 connects with the chamber contain ing valve 29 thereby communicating .with the passage 28 and extends `upwardly and has connection with a filling tube 34.

A regulating valve 35, provided with an extended valve stem 36, is contained in the passage 33 for the purposev oi regulating the iiow of liquid therethrough. A valve spring confined on the stem keeps .the valve in a normally seated position. The valve 35-36 is slidably confined within a bushing 37 screw-threadedinto the casting. The upper portion of the valve stem 36 Iis provided with an eye 38 and pivotally connects ywith a screw-threadedy stem 39 whichA carries a nut provided with a rounded or oval head 40. A valve actuating lever 41 is pivotally carried upon` the casting at 42 and adapted to remain in a normally "horizontal position. A slot 43a is provided .within 'the lever or through the triggermember 41 for the purpose of containing the upper portion of the valve stem. Asvlater shown the trigger or lever 41 will .exercisea regulating control over the valvey 35.

A trigger comprising a long .stem or rod 42 is mounted upon ythe table support which carries the machine. Thisi trigger member is vertically arranged and has its upper ex- 'oi the arm 44.

tremity lying directly beneath and in line with the outer end of the trigger 41. A short distance from the upper end of the trigger is provided a wedge shaped deflector step 43. This member 43 is formed on the trigger rod just beneath one arm 44 of a set 50. This arm restsupon the upper surface v One extremity. lies within an arcuate cavity 51 formed in the casting, while the outer extremity Yis provided with a pair of pins 52, one upon each side of the member-49. The pins 52 lie in contact with the vertical face of the trigger member and just above the inclined-plane v45. The triggerA member is slotted or split at this point where it passes upon each side of the member 44.

The four arms 44 are confinedand fixed upon two vertical actuating rods 53, such i that the devicewill be carried up and down during the vertical reciprocation of said rods. These rods upon which the machine is mounted are slidably confined within bearings 54 securely -ixed to the table or platform which mounts the device.

The complete assembly of all parts necessary to place this machine in operation would disclose a foot or hand lever operating means shown below the table or platformand having connection with the lower extremities of the rods 53. These latter parts are broken away and not shown since any formiof foot pedal or operating means suiiicient` to subject the rods to van interxmittent vertical reciprocation at times desired by the operator, may be used in connection with this machine.

The drawing illustrated herein may be taken to be a rear view of the device, which would place, the yoperator in front of the machine in a position convenient to the bot tles. In such a case the bearings 54 and rods 53 and all control devicesin connection herewithV would be partly in the rear of the maf;

chine withy all the principal working parts located slightly forward and away from the reciprocating rods andbearings.

In the` operation of this device yand the .Y

charging-.and the illingof .bottles therefrom, two bottles will be placed in position as illustratedrone directly beneath the opens i ing 16 and the packing glands, and the other arranged to the side thereofand directly un# der the open end of the pipe 25. The machine is supported above the table with just enough room to permit the bottles to be placed thereunder and readily removed.

In the upwardly limited posit-ion of the machine the water valve 35 is normally seated thus withholding the pressure orn the flow of carbonated water under pressure from the tube 34 which connects with the supply located any convenient distance from the machine. When the machine is thrust eownward by the usual form of toot power the packing gland l2 passes down around the 1oottle neck7 and as the machine comes down the lifting arm 49 with its parts 52 will ride along the cam e5 of the trigger thereby lifting upwardly the cap 13 which contractibly compresses the packing gland around the bottle neck thereby sealing same against liquid or air leakage. At the same time the trigger il is lifted which unseats the valve 35, thus permitting the flow of carbonated water under pressure through the duct 33 down into the passage 2S which leads the water directly into the bottle. The water passing into the bottle forces the air therefrom upwardly through the duct 28 into the chamber 2 above the piston 4 thus forcing the piston to descend. It will here be understood that the chamber 3 under the piston 5 contains the necessary syrup, flavorings or juices for the composition oi"v the soda pop in the bottle at the time of filling. The pistons 4- and 5 work jointly one with the other and as the air pressure from the bottle forces the pistons downwardly the syrup in the chamber 3 will he forced through the duct 277 by the valve 29 and into the bottle along with the water. the two liquids thoroughly co-mingling and mixing under the energetic action or the carbonated water under the usual carbonic gas pressure. At this stage of the operation the valve 26 will be closed to prevent the syrup passing out in that direction.

When the bottle has been filled the foot pedal7 or any form of operating mechanism used, will again loe brought into play by the operator and the machine further shoved down on the bottle. This will cause the crown or cover cap 22 to be brought in contact with the bottle neck, and under the pressure of the plunger 17 `backed up by the stiff compression spring 21, the crown 22 will be rammed upon the bottle sealing same under pressure. Simultaneously with this described operation the machine on its further downwardly displaced motion will cause the arm JC-1 to come in contact with the inclined plane 43 thereby causing the trigger rod 4:2 to be iexed or bent outwardly at its top end. This action causes the upper end to be forced from beneath the trigger 41 and permits said trigger to return to its downwardly limited position under the action o't the valve 35-36 and its spring.

This closes oif the water supply and permits the bottle to be crowned without undue wastage thereof. The machine will then be released which will permit it to rise to the position illustrated. The bottle will then be drawn from the device iilled and scaled.

This machine provides means for simultaneously passing the syrup and the carbonated water into the same bottle.. lt also 'provides means for passing the syrup into one bottle at the same time the water is being passed into another bottle. ln this latter inode or' operation a bottle la is setin a filling position beneath the pipe L15, and the valve 26 open. i screw B is screwthreaded into the casting with its head pass ing through the passage 27, 4thus plugging up and closing same. ln this way the syrup confined in the chamber 3 will be forced out through the pipe 25 and into the bottle A. while the water from the tube 34- will be permitted to flow into the bottle. ln this way the bottle C will be replaced in each operation by the bottle A, since the bottle will have the necessary quantity of syrup already introduced thereinto and will be placed under the machine merely for receiving its charge 01' carbonic gas and water. The machine is capable of being used in either manner as illustrated and described. i/Jhen the machine travels upwardly Vto its natural inoperative position, as illustrated. the parts all assume a normal position which permits the packin(y gland l2 to be relieved from its conipression thus loosening its hold upon the bottle neck. As the machine travels upwardly the valve will be drawn open by the suction of the piston 5 which permits another charge of syrup to be passed into the chamber 3 through the duct 30, and at this stage or operation a valve 32a, included in the pipe 25, will close thereby holding the syrup in the chamber until it is discharged therefrom through one of its selected passages, either into the bottle A or C according to the method of operation employed.

The invention is presented to include all such changes and modifications' in design or form as may come within the scope of the following claims:
